by the standard relation between the bulk spacetime and the tensor network that discretizes it [1]}, [2]}, as shown in fig:single. More so, when computing the Rényi entropy, there is an exact correspondence (including non-perturbative effects) between the single random tensor and the multiboundary wormhole when the horizon areas are fixed to a parametrically small window [3]}, [4]}, [5]}.Note that by non-perturbative effects we mean effects of \(O(e^{-1/G_N})\sim \chi ^{k}\)  for some \(k\) , i.e., power law corrections in the bond dimension.
